United States President Donald Trump’s administration has asked lawmakers to clear the sale of 48 F-35 fighter jets to Saudi Arabia for an estimated $24.3bn.

“This proposed sale will support the foreign policy and national security objectives of the United States by improving the security of a major non-NATO ally that is a force for political stability and economic progress in the Gulf region,” the State Department said in a statement on Thursday.

The administration said the sale of the jets, the most advanced fighter aircraft the US has, would “not alter the military balance in the region” in keeping with longstanding US policy that Israel must have a military edge over potential regional adversaries.

The announcement comes after the Houthis in Yemen claimed on Wednesday they shot down a Saudi F-15 fighter jet over Marib, a key city in their battle against Saudi-backed Yemeni government forces. The group released video of fighters in the city standing before burning wreckage of what appeared to be a US-made F-15 fighter jet with Saudi Arabian markings.

The Houthis claim the aircraft was shot down with a “locally made” surface-to-air missile, which would mark a dramatic change in the group’s ability to wage war in the area. Until now, Saudi Arabia’s military has enjoyed relative air superiority in Yemen, and has relied heavily on its ability to carry out air strikes in the neighbouring country.
